BUTTER-CUTTER.

To all whom it may concern:

Be it known that we, Fnnnnnron J MAC- NISH and WILLIAM E. PENN, citizens of the United States, residing at Oak Park, in the county of Cook and State of Illinois, and Lakemills, in the county of Jefferson and State of Wisconsin, respectively, have in vented certain new and useful Improvements in Butter-Cutters, of which the following is a specification. 4

This invention relates to improvements in machines for cutting bulk butter into prints. While some features of the invention are applicable to butter cutters generally, other features are more especially applicable to machines of the type described in Patent No. 845,468, issued to us on February 26,1907.

One of the objects of the present invention is to provide means for preventing further relative movement between the butter and the cutting devices after sufficient movement has occurred to produce prints of the desired size.

Another object is to provide automatic means for permitting relative movement between the butter and the cutting devices af ter the prints previously out have been removed from the machine.

A further object is to provide means for positioning the butter-containing box in the machine.

The invent-ion also relates to the other improvements in butter cutters hereinafter set forth.

I11 the accompanying drawings, Figure 1 is a side elevation, with parts broken away, of a butter cutter embodying the features of our invention. Fig. 2 is a front elevation,

partly in section, of said machine. Fig. 3 is an under side view with the supporting legs omitted. Fig. 4 is a sectional view taken on the plane of dotted line 4 4 of Fig. 1.. Fig. 5 is a fragmental view of the stationary cutter frame and adjacent parts. Fig. 6 is a section on line 6 6 of Fig. 5.

The embodiment herein shown. of the invention is designed for use in creameries and other places where large quantities of butter are cut into prints or cakes. The butter is packed in rectangular boxes provided with removable bottoms, enough boxes being pro- Specification of Letters Patent.

vided in practice to hold the days output. After being filled the boxes are placed in the refrigerator, in order to harden the butter.

The supporting frame of the machine comprises a table 1 upon which a butter box 2, filled with hardened butter, as just explained, may be placed. The open forward end of the box is arranged to abut against the stationary cutter frame 3, which frame'is substantially rectangular and is provided at its lower corners with extensions or lugs 4 (Figs. 1 and 3) adapted to fit into recesses 5 in the opposite sides of the supporting frame. The stationary cutter frame 8 is secured rigidly in position by means of set screws 6 and 7 mounted in the supporting frame and arranged to bear against the extensions 4. It will be noted that the set screws 6 are ar ranged to act longitudinally of the cutter frame 3, thus constituting means for obtaining an endwise adjustment of the position of said cutter frame in the machine. Referring to Fig. 2, the adjustment just mentioned is from right to left and vice versa.

The height of the cutter frame 3 may be adjusted by means of set screws 8 mounted in the supporting frame and bearing against the lower bar of said cutter frame, as indi cated in Figs. 3 and 5. The horizontal and vertical cutting wires 9 are secured in the cutter frame 3 in any suitable manner. Said frame is provided upon its inner sides with lugs 10 against which the forward end of the butter box 2 bears.

In order that a succession of butter boxes 2 may be quickly and accurately positioned on the table 1, vdth reference to the cutting mechanism, we provide two slides 11, (Fig. 3), carried upon the under side of said table, each of said slides being provided with a jaw 12 adapted to lie at one side of the butter box. Said jaws are moved into and out of engagement with the box by means herein shown as consisting of a pivoted plate 13 (Fig. 3), said plate being connected with the slides 11 by means of links 14. 15 is a hand lever fixed to the plate 13 and extending outwardly to a point within convenient reach of the operator. The jaws 12 afford means for positioning the box centrally of the table 1. For moving the box into posi tion against the stationary cutter frame 3,

box.

we provide a jaw 16, slidable upon the table 1 and arranged to engage the rear end of the Said jaw is provided with a shank 17 extending through an elongated opening 18 in the table, which shank is pivotally connected with a crank 19 fixed upon a shaft 20 the latter bears at its outer end a hand lever 21 by means of which the jaw 16 may be moved to push the box against the cutter frame. The means for forcing the butter out of the box 2 and against the cutting wires 9 will be described hereinafter.

Slidably mounted upon ways 22 (Figs. 5

and 6) on the forward portion of the sup porting frame, is a carriage 23 which, in the form herein shown, comprises two end pieces 24 rigidly connected together by a bar 25. .ln order to insure that the carriage 23 shall have a true rectilinear movement, free from any rocking or shaking on its ways, we provide shoes 26 carried by set screws 27 extending through the bar 25, said shoes bearing upon ways 28 formed on the supporting frame below the ways 22. The shoes 26 may be adjusted by means of the set screws 27 to take up any wear that may occur.

Rigidly attached to the rear ends of the end members 24 are uprights 29, the upper ends of which are joined by a rod 30. The uprights 29 are slotted, as at 31 and have ways 32 and 32 formed thereon. A movable cutting member, herein shown as a wire 33, is fixed at its ends in two yokes 34. Each of these yokes is provided with two rollers 35 adapted to travel upon the ways 32, and two rollers 36 to travel on the way 32". Each roller 35 comprises two ortions running on the ways 32 and a cy indrical portion 35 of larger diameter extending into the space between said ways. One of the yokes 34 is provided with a handle 38 by means of which the cutting wire 33 may be moved up and down.

The yokes 34 are connected to move together by means herein shown as comprising a rock shaft 39 mounted in bearings 40 upon the machine frame, said shaft carrying at opposite ends crank arms 41 which are connected with the yokes 34 by links 42. When one of the yokes 34 is raised by means of the handle 38, the connections just described cause the opposite yoke to be similarly moved.

The butter that is forced through the stationary cutter frame 3 may be received upon a spreader tray 43 of any suitable construction, which tray is herein shown as tiltably supported upon the carriage 23 by means comprising an arm 44 which is fixed to a rock shaft 45 carried in bearings 46 upon the carriage. Said arm has near its upper end a bearing 47 in which is slidably mounted the stem 48 of a frame 49. 50 is an adjusting screw extending through the arm 44 and engaging the frame 49. The latter comprises wire 33 may be adjusted by changing the position of the frame 49 with respect to the arm 44, such change being made by means of the screw 50. The slpreader tray 43 may be adjusted to lie para lel with the path of movement of said cutting wire by means herein shown as bars 53 adjustably secured to the ends of the frame 49, said tray resting,

not directly againt said frame, but against said bars. The adjustment between the frame 49 and the bars 53 may be obtained by means of screws 54 extending through elongated. opening 55 in said bars into said frame.

The arm 44 is locked against tilting move ment by means of a hand lever 56 pivoted at 57 upon said arm, the lower end of said hand lever being adapted to lie within a socket member 58 (Fig. 6) fixed to the bar 25 of the carriage 23. A spring 59 tends to hold the lever 56 in locking engagement with said socket member. Stops 60 upon the arm 44 limit the pivotal movement of the lever 56. The socket member 58 has an inclined edge 61 to direct the lower end of the hand lever 56 into said socket. The rearward tilting movement of the arm 44 is limited by suitable means such as a bracket 62 fixed in the machine frame, said arm striking the upper end of said bracket.

The means herein shown for forcing the butter through the stationary cutting frame 3 comprises a platen 63 fixed to the forward end of a rack bar 64, said rack bar being supported in a bracket 65 fixed to the machine frame. The rack bar 64 meshes with a pinion 66 rotatably supported in the bracket 65. Said pinion is rigidly connected with an internal spur gear 67 meshing with a pinion 68 fixed upon a shaft 69 rotatably supported in the bracket 65. To the shaft 69 is attached a crank arm 7 O by means of which the train of gearing just described may be actuated to move the platen 63.

If desired a yielding connection may be provided between the crank arm 70 and the gear train to cushion sudden stoppage of the platen. The crank arm may consist of two sections 7 0 and 7 0 pivotally connected at 71, the inner end of the section 70 bearing against a coiled spring 72 seated in a recess in the section 7 0*.

It is desirable to provide means for automatically preventing the extrusion of butter through the cutter frame 3 when the quantity necessary to make bricks of the de lSQ sired size has been forced through said frame. It also is desirable to provide means for automatically putting the machine in condition for another operation when a tier of prints has been cut and removed. In the present embodiment the means employed to attain these ends comprises a plurality of locking dogs 73, of differing lengths, pivoted side by side in the bracket and adapted to engage locking teeth 74 upon the spur gear Wheel 67. A plurality of dogs 73 of varying lengths is preferably employed in order that one of said dogs may always be able to drop directly behind one of the locking teeth 74 and thus prevent lost motion or backlash. The dogs 73 tend to gravitate into locking engagement with the spur gear wheel 67 The means herein shown for permitting said dogs to move into locking engagement and for moving them out of such engagement, comprises rock shaft 75 eX- tending longitudinally of the supporting frame and provided at its rear end with an arm 76 which supports a plunger 77 vertically movable in a bearing 7 3 in the bracket 65. Said plunger is provided at its upper end with a yoke 79 in which lie the rear ends of the locking dogs 73. The down ward movement of the arm 76 is limited by the stop portion 30 striking against the machine frame. The forward end of the rock shaft 75 carries a crank arm 81 adapted to underlie an arm 82 rigidly connected with the arm 44.

83 are lugs (Figs. 1 and 3) on the angular portion of the frame 49, lying at opposite sides of the arm 82. They assist to hold said frame in position upon the arm 44, and slide along the arm 82 when said frame is adjusted by means of the screw 50.

The carriage 23 is moved rearwardly (to the left Fig. 1) by the pressure of the butter forced through the cutter frame 3, until the arm 32 is moved off the crank arm 31, when the locking device is operated. After the butter has been out vertically with the cutter 33, the arm 44 is tilted downward against the bracket 62 to lower the prints into convenient position for removal. In order automatically to restore the carriage to initial position, we provide means such as an arm 34 pivoted to the arm 44 and extending freely through an opening in the bracket 62. Said arm 84 has a projection 85 to contact the bracket 62. When the arm .44 is tilted downward, the projection 85 strikes against the bracket, and the carriage 23 is pushed into its initial position. Preferably the bed of the machine is inclined, as indicated. in Fig. 1, in order that the spreader tray and the severed tier of prints shall be stable when in position on the .iaehine.

In operation a butter tub 2, filled with hardened butter, is set upon the table 1, centered by operating the hand lever 15, and

moved into place against the cutter frame 3 by means of the lever 21. The bottom of the box having been removed, the platen 63 is inserted in the box, and the crank 7 O rotated to force the butter through the cutter frame 3, the wires 9 of which cut the butter on horizontal and vertical planes. The rotation of the crank is continued until the butter, impinging against the spreader tray 43, forces the carriage 23 rearward until the arm 32 has been moved off the arm 31, whereupon the rock shaft is rocked by gravity, permitting the dogs 73 to rise into locking engagement with the spur gear wheel 67. Further rotation of the crank 70 is therey prevented. The ll1(-.Cl1t.'fllSlllS are so adjusted that the looking action takes place when sufficient butter has been er-cpelled from the box to form prints of the de sired size. The operator now moves the cutting wire 33 by means of the handle 38 to cut off a tier of prints, said prints resting upon the spreader tray 43 and the angular portion 51 of the frame 49. The hand lever 56 is now tilted to the eft (Fig. 2) to withdraw the lower end of said lever from the locking socket The frame 49, with the spreader tray 43 and butter prints resting thereon, is now free to he tilted upon the axis 45 until the arm 44 engages the bracket 62. As the fram 49 is lowered the carriage is returned to its initial position (Fig. 1) through the engagement of the arm 84 with the bracket 62. The spreader tray 43, with the prints thereon, is new removed from the machine, and another tray placed upon the frame 49. Said frame is then tilted into the position shown in Fig. 1 and secured in said position by the engagement of the hand lever 56 with the socket member 58, said lever engaging said socket as the frame is tilted. As the frame 49 is thus raised into its normal position, the arm 32 depresses the crank arm 31, rocking the shaft 75 and unlocking the butter-moving mechanism to action. The crank 70 may now be rotated to force butter through the stationary cutter frame 3, as before.

it wih be noted that when su'flicient butter for a tier of prints has been passed through the cutting frame 3, the butter-moving platen is automatically locked against further movement, and that said platen is unlocked as soon as the prints have been cut and removed and the carriage 23 placed in position to receive another tier of prints.
